To ad 'zo/tom it may concern.: V f' 13e it known that l, CHARLES \V.-Z1EoLEn, a citinen of the United States, residing at l Scranton, 1n the county of Lackawanna and State of Pennsylvania, have invented certain 11e/Wand useful Improvements in Coal-Sepators; and I do hereby declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertai ns to make and use the same.

My invention relates to coal -separators adapted for separating slate and other impurities from coal after the latter has been sized by the usual screening process.

The present invention is designed as an improvement upon the apparatus shown and described in Letters Patent of the United States heretofore granted to -me as follows, to wit:

`No. 277,530, dated May 15, 1883; No. 291,123,

dated January 1,1884; No. 380,156, dated March 27, 1888, and No., 570,781,-`dated N07 vember 3, 1896. The same broad parigiiple of operation is involved in all ofthe patented machines' above referred to, the-coal containing slate or-other impurities being directed along an inclined surface 'provided with transverse openings through which the slate or other impurities drop to independent troughs or receptacles, the difference in shape and 'specific gravity of the coal and slate causing the former to travel upon the inclined surface at a greater speed and momentum than the latter, with theresult that the slate readily -drops when an interruption in the continuityV ofthe surface is encountered, while the nmentum of the traveli-n".r coal carries it over such point of interruption for delivery into a receiver located in advance of the receptacle into which the slate falls.

The apparatus to be described hereinafterI is based u pon the saine principle of operation,

surface improved adjusting means for .regu' lating the inclination of said plates and for varying the size ol' the openings between the plates.

The construction of the improvements Will be fully described in connection with tho accompanying drawings, which constitute a `part of this speclioation, andalimevelftcatures will be defined in the appended claims.

` I.n the drawings, Figure 1 'isa side` eleva` tion of a coal-separatorembodying myinvention. Fig. 2 is a top plan view of the same. Fig. 3 is a top plan view of the gage-plates and their connecting-bars. Fig. 4 is a section on the line o o of Fig. 3. Fig. 5 is a detail perspective view illustrating the means for supporting the plates or sections forming the` surface upon Vwhich the coal travels. Y Fig. G is a vertical longitudinal section of the apparatus. Fig. L7 is a vertical section of one of the surface plates, showing `its convex projections. Fig. S is a detail vertical section shoufing the inner side of the frame of the machine.

Figs. 9 and 10 are detail detached views of n parts shown in Fig. S. Fig. ll is a section on the line u u of Fig. S. Figs. 12,13, 14, and 15 are sections on the lines ne, -g/ y, a', and 1u fr, respectively, of Fig. G; and Fig. 16 is a perspective View of one of the rods for supporting the convex-surfaced plates and its projecting bracket.I l

The reference-numeral l designates the supportiugr-framework of the apparatus, 2 the slate-discharging chute secured to the frame, and 3 the frame Within which the separating mechanism is supported.

The incline for the coal, as best shown in Figs. 2 and G, comprises a plurality of sections or plates, the upper one, 4, 4of which is A preferably perforated to permit of the escape of dir t from the coal as it falls upon the incline. rlhe remaining plates 5 are imperiorate and provided upon theirupper surfaces with rows of convex projections 6, (see Fig.

7,) which impart to the plates a surface over t slate.' Below the lower end of each of the plates Ais arranged a transverse bar 7, supported adjustably byvbolts 8, which extend through the frame 3 and are held at their uppere-nds by nuts,while their lower ends 9 vare bent at right angles and secured to the undersidesof-the-bars 7. Thelpwere'nds of the plates are' secured to these bas' 7 by screws 10 or other suitable means, and the upper` sides of said bars are longitudinally Vrecessedjto forniA Aseats 11 forr. cylin,der s .12, which are preferably hollow, as shown," and secured to the bars'by bolts 13. 4'lfhe upper ends14 of the p1ates5 are bent downward at right angles, andoverlapping each vOfsaid upperjends Vis a gage-plate 15, bentat right 'angles 'ftp fitove'r the'plates 6, .as shown in- Figs. Land 6p; Theends of these'gage-plates project through openings inthe sides of the frame 3 and are'conne'cted -by bars 16, provided with laterallyiex'tending journals 17',

.whichextendthrough the sides ofthe frame and are supported in "slots 1.8 in the'upper ends; of ,levers 19, secured-'on the ends ot" a rock-shaft 20. This shaftiZOis mounted in 4be'9. 1 ngs of the frame, hndore of the levers 19 is extended below its connection with the` rock-shaft 20 and connected bya'lnk 21 to perat'efthe gage-platesfto control the size of e the openings between theplates 5.

The-upper ends of the plates 5 rest loosely' upon Vangle-brackets 26j; projecting from the j lov ifelfends of adjusting-rods 27, which' extend 4- arehel'dbynuts28,engagingtheupperthread- ',edends of said rods.'

-As shownin Figs.` Sand 11, the-side walls Plitt@ 'L ofthe incline' is hinged at'it's lower end toafcross-barf23 and Vis adapted to be operated by a lever 24, connected 4 by a systempf 1ink`s25.

vertically through 'the sides of the frame and- .of the frame Biare` suitably'rec'essed at the ints 29 and. 30 Vto permit of the required vertical movement of the adjusting devices-l "of the plates, and sliding plates 31 protect said recesses from the entrance of dust and I dirt orsmall pieces ofcoal whenthe vertical .15o

har is lowered.

1., At each side of the frame 3 is arranged a guard-plate 3 2, having edge slots, as 33,19

i do

adapt the guard-plates to fit over the plate- ,1 supporting devices.` f S5 The operation of the apparatus will be read;

ily yunflerst'ood and maybe briefly described fas follows: The coal, withits contained slate, -falls upon the upper plate 4 of the incline (see Fig. 6) and passes by gravity over thesuccessive plates 5. The slate passes vover paratus,

to the plate e Y s2503204 the` cylinders 12 and drops intdthe slatechute, as indicated by the bent arrows, while the coalis carried by its momentum over the cylinders and finally discharged 'through the coal-chute at the lowerend of the incline.

It will be apparent that the inclination of the plates vmay be raricfdfor different grades and qualitiesv olf-"coal and that 'the width of the openings between the plates maybe likewise varied'to suit the exigencies of the work. I t will alsobe observed that the angular form :of the lgagelplates` prevents tlel engagement ofthin Yflat piec'esof coal 'or slate under said plates and theconseluent clogging of the ap'- 'Iz entimf-v v 1f.
